Chromeleon 6.8 – Data Analysis

Get More Information from your Samples with Advanced Data Analysis Capabilities

If your work is more challenging than routine chromatography, you need more powerful analytical tools than the ones available with most data systems. The capabilities of Chromeleon® go well beyond the basics to help you through your toughest challenges.

Diode-Array Data Analysis

With the optional Chromeleon PDA license, you can acquire full-spectrum data from selected diode-array detectors. Those data can then be processed on any Chromeleon client station for 3-D data rendering, peak purity analysis, and compound identification based on spectral library matches. All of these capabilities are fully and seamlessly integrated into Chromeleon—you never feel like you're working with a separate piece of software.


With the MS option, Chromeleon offers full control, data acquisition, and data processing for the Thermo MSQ and AQA mass spectrometers. You can check the mass spectrum of an eluting peak in real time, compare mass spectra corresponding to different chromatographic peaks—even overlay TIC and SIM chromatograms with data from UV, fluorescence, and conductivity detectors to confirm analyte identities and spot impurities.

Custom Sample Variables and Peak Variables

Access the full power of Chromeleon's built-in spreadsheet using Chromeleon's optional Report Publisher. Add columns to the sequence to store lot codes, expiration dates, sampling points, special correction factors, and other variables that have a correspondence of one per sample. Add columns to the peak tables to store calibration standard descriptions, purity factors, stability factors, and other variables that differ from compound to compound.

Custom variables can be any of several data types (text, integer, floating point value, date/time field, or "pick list"), and once defined, are available throughout the software for labeling, calculations, database queries, and reporting.

Custom Formulas

With Chromeleon's optional Report Publisher, you can access the full power of Chromeleon's built-in spreadsheet. Create your own formulas in standard Microsoft Excel syntax, using a library of over 120 worksheet functions such as IF, AVERAGE, STDEV, and LOOKUP. Use cross-references between worksheets to share calculated values across multiple report sections, or to separate intermediate calculations from the final presentation. And because the Report Publisher also supports charting, you can present results graphically for easier interpretation.

Software Development Kit

Want even more flexibility? Need a completely customized user interface, or a solution that integrates Chromeleon with other software products? The Chromeleon Software Development Kit (SDK) gives you the tools you need to develop such custom solutions. Using Visual Basic, C++, Delphi, or any other programming language that supports the component object model (COM), you can read and write Chromeleon data structures and system variables, and make function calls to perform a wide variety of automation and data processing tasks. With the Chromeleon SDK, the possibilities are limited only by your imagination and programming resources.


Three-dimensional data analysis features are seamlessly integrated into Chromeleon, so you never feel like you're working with a separate software product.


With its friendly user interface and powerful analysis capabilities, Chromeleon makes LC/MS practical for a broad range of chromatographers.


Define your own custom variables to store lot codes, expiration dates, purity factors, and other data relevant to your specific application. Use the variables anywhere you like in Chromeleon—in calculations, reports, even peak labels.
